The vapor shock absorber is a damaged accessory during the use of the car. The work of the shock absorber is good or bad, which will directly affect the stability of the car and the life of other parts. Therefore, we should make the shock absorber often in a good working state.When a bumps occur, the shock absorber emits the sound of "stun" or "creaking". When the car is driving slowly and emergency braking, if the car vibration is more severe, these phenomena indicate that the shock absorber is broken.Here are the common faults and maintenance of shock absorbers in detail.
The harm of the car shock absorber is broken
Car shock absorption has leaked oil. If you dont change it, there are still a lot of disadvantages.
1. If the shock absorber does not change the oil, long -term driving will reduce the shock absorption effect of the car, cause an abnormal noise when the vehicle is driving on the bumpy road, damage the entire suspension of the car, and cause the car suspension to deform.
2. In addition, if the shock absorber that does not change for a long time will also affect the comfort of the ride.
3. Oil leakage of shock absorber will cause uneven force on both sides of the tire to cause the vehicle control to be blocked, and it will cause faults such as tires to run bias for a long time.Finally, the cost of repairing the car is much higher than the cost of shock absorption.
Therefore, in general, as long as the oil absorber is leaking, it will become more and more serious, so we still recommend that replacement in time is the best choice.
Common faults and maintenance of shock absorbers
How to check the shock absorber
1. Observe your car, especially the previous part
This is relatively simple. You only need to drive the car to a very flat road to ensure that both sides of the car are at the same height.If you know the specifications of your cars suspension, you can try to test whether it is that height.If this height is not in normal specifications, it is likely that there is a problem with the shock absorber.At this time you should do a professional assessment and repair for your car.
2, rebound test.This is a relatively simple and practical method.
First, stand in front of your car; be careful of your feet or knees on the surface of the bumper bending, and your hands along both sides to push the car hard.Third, quickly evacuate your feet or knee.Fourth, observe the reflection of the car.If the car rebounds continuously, it means that your shock absorber is broken.If the car rebounds to the original position without continuing to rebound, it means that the shock absorber is good.In the state of empty cars, park the car on the flat flat road to make the car in the empty state.The inspectors stood at the four corners of the car, and pressed the hands from the corners of the car. They suddenly loosened their hands when they couldnt press it. At this time, pay attention to observing the backbone of the body.If the rebound is timely, the body will be restored after the rebound, indicating that the shock absorber is in good condition.On the contrary, if the rebound is slow and the body is repeatedly fluctuated before it gradually returns to the static, it proves that the shock absorber effect is poor, and it has even failed.
3. Observe the shock absorber directly with your eyes
There is also a common indicator to check whether the installation point of the shock absorber is intact and whether the shock absorber is corroded.Observe whether there is a humid phenomenon on the shock absorber. If the surface is really humid, it means that the liquid leakage in the shock absorber is revealed, and it needs to be replaced at this time.Another point is that you need to drive the car into the garage to confirm your observation and whether you need to replace the shock absorber.Note that you need to confirm whether the liquid you observed really comes from the sealing leak of the shock absorber, because it may be the surface of the shock absorber.
Common methods of judgment in daily life
1. Make the car on the road with poor road conditions for 10km and stop, and touch the shock absorber shell by hand. If it is not hot enough, it means that there is no resistance inside the shock absorber and the shock absorber does not work.At this time, you can add appropriate lubricating oil and test. If the shell is heated, it is the oil deficiency inside the shock absorber, and the oil should be added, otherwise, the shock absorber will fail.
2. Press the bumper hard and loosen. If the car jumps 2 to 3 times, it means that the shock absorber is good.
3. When the car is driving slowly and emergency braking, if the car vibration is more severe, it means that there is a problem with the shock absorber.Generally damaged causes are oil -sealing cushions, sealing cushions rupture damage, the storage cylinder caps loosen, the gap between the piston and the cylinder tube becomes larger;Whether the device is connected, connecting rods, connecting holes, rubber, bands, etc. is damaged, welded, ruptured, or shedding.
In addition, the shock absorber will cause a sound failure in actual use, mainly due to the collision of the shock absorber and the steel plate spring, frame or shaft phase, damage or falling off, and the deformation of the shock absorbers, oil and oil, oil and oilCauses such as shortcomings.Then if the shock absorbers are prevented as ordinary car owners, the method of preventing the shock absorber from invalidation is to prevent the non -normal wear of the hydraulic sealing ring of the shock absorber, so that the shock absorber life will reach the specified cycle of the vehicle.
Method to prevent shock absorber failure
1. Reduce the amplitude.
When choosing the pavement, the owner chose as flat asphalt road as possible, and intentionally avoided the more ups and downs of damaged severe roads and sandy roads.
2. Slowing the amplitude.
When roadblocks such as deceleration bands, slow down slowly, otherwise the shock absorber will have a large amplitude.
3. Avoid overload.
The overload will allow the reverse force of the shock absorber to reach the limit value. This will not only make the shock absorber lose the shock absorption effect, but also cause the hydraulic oil rubber sealing ring to deform under the action of hydraulic pressure, thereby exuding the oil.
